1.4.9 Incomplete

- opening up some functionality for Addin_button to interact with
- when user adds Notes to Storyboard/GroupEm, notes now have custom
icons
- able to export files to RTF and import RTF files (useful for template
snippets)
- toolbars all collapse into a single toolbar on Layouts (still need to
add an option for this)
- ctrl + w shortcut expands app across both screens (and CORRECTLY now,
in terms of positioning)
